Abstract
Immersion of maiden apple root stocks (East Malling VII and IX) in water at 115°–116°F. for 30 minutes killed Pratylenchus penetrans, (Cobb, 1917), Filip. & Stek., 1941, within the roots. Damage to the plants was reduced or prevented by cooling in tap water immediately after treatment. The nematodes were killed more rapidly at higher temperatures, but the plants were more easily damaged. Older plants with larger root systems required longer treatment. Plants treated immediately before planting suffered more injury than those taken from cold storage at 34°–38°F. for treatment in January and returned to cold storage until planting time in late March.
